Would you hope to get around a country without a map? No!
Well search engines and site visitors are no different, they want to see a map on your site so they can get around it. Search engines in particular want to find all the little nooks and crannies that make up your site.
Sitemaps are often ignored or treated as the least important thing on the site and yet Google think they are reasonably important.
So who am I to argue with him?
Because I know that you are going to be wondering how to make the Google gods happy I decided to help you.
You get sitemap plugins to cover both parts of the Google equation all in one package. Take a look at it and if you don’t already have it then look at my Wp Easy Ads plugin as well
